LR-A029 Digital Display Oxygen Index Tester

1、Use

Mainly used for evaluation of the combustion performance of the polymer under specified

test conditions, the determination of polymer just maintain minimum volume percentage of

oxygen concentrations of combustion.Suitable for polyurethane materials, flame retardant

wood, plastic, rubber, fiber, plastic foam, heat preservation material, film, artificial leather and

film, and the combustion performance of textile materials such as determination.And can be

used in building materials B1, B2 level performance measurement.
